<DIV><FONT face=Courier size=2>Hello Fellow Mythees,</FONT></DIV>
<DIV><FONT face=Courier size=2></FONT> </DIV>
<DIV><FONT face=Courier size=2>Last week, I posted about having grainy, delayed
audio while watching LiveTV. BJM offered me a very prompt response, but --
hothead that I am -- I had already wiped by box clean and cursed Fedora.
:-) I'm back up with Gentoo and have Myth up-and-running. Video
quality is substantially better than it was after my first attempt and I'll
continue to try and tweak it. There are some lingering issues with
MythVideo, but they are relatively minor and I'll post another time if I can't
resolve them on my own. The audio problems, however, continue to rear
their ugly heads.</FONT></DIV>

<DIV><FONT face=Courier size=2>Running Gentoo 2.4.25 kernel on an Athlon XP
2400+. Using onboard sound (Via) and have a BT878 tv-card. The TV
card's line out goes to my onboard line-in.</FONT></DIV>

should?).</FONT></DIV>

<DIV><FONT face=Courier size=2>Problem:</FONT></DIV>
<DIV><FONT face=Courier size=2>Watching Live TV or recording TV is near
impossible because the sound is terrible. It's grainy, clipped, and speech
is difficult to comprehend. Everything is in sync though -- which I guess
is a good thing. Also, Myth has ALSA support (I did an ldd as you
suggested and came up with the following: libasound.so.2 =>
/usr/lib/libasound.so.2 (0x40ca4000)), but I can only select between /dev/dsp
and /dev/adsp when selecting sound options. Furthermore, when I run
mythfrontend, it states the following:</FONT></DIV>

server: 127.0.0.1:6543 (try 1 of 5)<BR>2004-05-12 15:32:26 Opening OSS audio
device '/dev/dsp'.<BR>2004-05-12 15:32:26 Using XV port 78</FONT></DIV>
<DIV><FONT face=Courier size=2></FONT> </DIV>
<DIV><FONT face=Courier size=2>OSS? I want ALSA -- or at least I thought I
did. I just want intelligible sound. :-)</FONT></DIV>
<DIV><FONT face=Courier size=2></FONT> </DIV>
<DIV><FONT face=Courier size=2>Other sound oddities that may yield
clues:</FONT></DIV>
<DIV><FONT face=Courier size=2>ALSA Mixer settings don't automatically restore
themselves even though I do an alsactl store. I don't know why this is the
case. It also seems like different applications play at different volumes;
while I'm aware that some apps have their own volume controls, I don't think
that's the problem. For example, I aplay and alsaplayer play at a much
lower volume than MythTV is I start them up without any config changes. I
suspect it's because one the first two are using ALSA while Myth is using
OSS.</FONT></DIV>
<DIV><FONT face=Courier size=2></FONT> </DIV>
<DIV><FONT face=Courier size=2>Outside of TV-related stuff, sound is
excellent. There is no way that the TV card would have
sound that would be THIS bad, so I suspect I'm not doing something
correctly.</FONT></DIV>
<DIV><FONT face=Courier size=2></FONT> </DIV>
<DIV><FONT face=Courier size=2>Suggestions, advice, guidance, tricks, tidbits,
and the like are both welcome and greatly appreciated.</FONT></DIV>
